Dear best guys, I really love 5.3 in many ways but here're some unbelievable transfer rates, after I went out and bought a pair of Intel GigaBit Ethernet Cards to solve my performance problem (*laugh*): (In short, see *** below) Tests were done with two Intel GigaBit Ethernet cards (82547EI, 32bit PCI Desktop adapter MT) connected directly without a switch/hub and "device
